, UNITEDsTATnSjgTENTOFFICE .I ofnnfrrcnanx, or. Pra-ova, Uran.

citizen `of the United States, residing at Provo city,` in the county of Utah andState of Utah, have invented certain new and useullmprovements in Resilient Tires for Vehicles,of which the followingisl aspecifica tion.` 'A i ;My inventionrelates to vehicle tires, and has for its" objectto provide ai tire which may bey-:expanded by mechanical means'rinstead of' by pneumatic inner tube that is.. now commonly' used, and to provide" atire which will notcollapse'if punctured and will lbeexible andresilient;A Theseobjects Iaccomplish with the device illustrated in` the accompanyin drawings in whichsimilar letters of re erenceindicate like parts throughoutthe several iguresand as describedin the specifications forming a part of this application, land as pointe out in` the appended claims. t

The preferred'form of my invention is shown in the drawings in which-t Figure 1 isa transverse section on a radial line, before the tire i'sexpanded;1 Fig'. 2 is a vertical section ofthe same after the tire is expanded. Fig. 3 isa fragmentary view of a section of myltire on line :v of Figui.. Fig. 4: is a-planiview, much diminishe of one of the guide bands.

My tire consists of an outer casing 1 Within which an endless spring band 2 `is built in and made a part thereof. Said casing 1 has th'ed es thereof made thicker and a lug or ribl3 ormed thereon. Within said casing 1 are placedand spaced apart two metal bands 4 and 4', and it `is not at` all necessary that they `arei composed of spring metal.V Saidband 4 has an extended ange 5 thereon at right angles to the axis of said handI and also an extended flan e 7 curved from the plane of `said band. aid band 4 has an extended flange 6 thereon at Vright angles to the axis of said band and a flange 8 on the other edge thereof, curved from the planeet said band. Through the flanges 5 and 6 are provided threaded o en` ings, within whchthe end portions o the :turn-buckles V9 'en age.

One end of each of said turn buc es `9 is threaded `to the ri ht as shown at 10 and the otherto the legt as shown: at 11. Secured on the peripheric face .of said ange 5 `of the band '4* iis a circular bandb;r means ofil threadedtap?- nuts 13. 401x the outer face of saidiband..;f12

is secured a circular cushion band 14. The edge .of said band 12 opposite the tap nuts 13 rests on the peripherlc face of said flange 6 `of the band 4". Within and adjacent said bands 4 and 4 are placed the circularench less guide bands 19, each of which has an inwardly extended flange 20. Within said guide bands 19' are placed the annular bands cutor formed in the peripherie face thereof, within which channels aretted the'edges ofksaid` outer casing 1. The outer side oi? each ofsaid, channels 21 engages the lugs 3` on` the edgeiof said outer casing. Said annular bands 15 and 16 have alined openings therethrough, within which openings are placed `the threaded bolts 17; and `by means of said threaded bolts 17, said bands 15 and 16 are drawn together, thereby bindyingsaid casing 1 into tubular form, :is

shown in Fig. 1. Said threaded bolts 17 are held in place by the nuts 18 screwed thereon. To draw said spring band 2 into, and to hold it in, concentric relation with the bands et andd, the turnbuckles 9 are rotated. Said rotation or turning of said turn buckles Si with the :right and left threads yon the ends thereof engaging within the threaded open ings in said bands 4 and d', will Widen the space between said bands, -and said casing will be made to assume the position shown in Fig. 2.` The said inwardly extended anges 2() hold said guide bands 1?) in fixed relation to the annular bands 15 and 16 and provide a mtal contact for the outward slidingof said bands 4 and l1 on the inner tid.

side of the casingl. The band 12 forms a closure for l`the inside of the tubular casing 1 and prevents gravel, iti and water from entering the interior o the tire when used on the road. The circular cushionband 14, secured on the peripherie face of said band 12, is provided to act as a cushion or bumper for the inside of said casing 1 ,and make any contact noiseless should the compression be i great, or the wei ht of the load carried by thevehicle be suc as to compress the spring bandv 2 to such an extent that the inner annula; face `of the lcasing 1l would contact withthe expanding elements. The widening ofthe space between the two bands f1 and 1" and the holding of them apart by the turn-buckles 9, secure by mechanical means,
